Weird that they only started putting it on them in 2011. My 2006 has MDS and seems to work between 35-70mph for the most part, or when the engine rpm is below 2000.

Right now, traffic lights often do the opposite of what they were intended, which was to help traffic flow. In fact, in some areas, that's intentional as the mindset is to use them to slow traffic down.

The problem is, the opposite affect happens when people sit at too many lights for too long. Often, they literally race from one light to another, hoping to occasionally beat the cycle. So, not only do people use more fuel starting off quicker than they normally would, but the end up sitting longer by getting to a stop light sooner.

Where I live, there's one traffic light that should be the model for every other light. It not only senses when a car is waiting at a red light, but also monitors traffic both on the main and side roads. What that means is, if I miss the light coming out of the side road, but traffic on the main road is light or even non-existent, I'll get a green light immediately. If traffic is heavy on the main road, but cars get backed up to a second trigger further back on the side road, it will wait longer to change, but not quite a full cycle. If the side road is nearly empty, but traffic on the main road is heavy, the full cycle will be given. Likewise, if there's a lot of traffic on the side road coming out on the green, the light will stay green longer on the side road to clear more of it. If there are only a couple cars, the green for the side road will shorten.

If more lights took the actual traffic flow into account, we'd save a ton of gas yearly.
This i agree with, even if some areas made the effort to just sync the traffic lights they have that are dumb would make a difference.

No doubt.

The ones that drive me bonkers are those short intersections between two lights where you have the first light turn green, but the one 20 yards ahead is still red, meaning you end up with traffic bottle necked across the first intersection. Just as bad is the opposite situation where the second light turns red first and the same thing happens.

Of course, any light that is strictly a timer is always a nuisance.

Actually, MDS first debuted in the 2005 models. Had it in my '05 WK, and '05 300C.

I'm not familiar with the previous generation JGC, so if they had MDS on earlier vehicles, I apologize for not knowing about it.

Around here the state is replacing traffic lights on heavily travelled road with traffic circles (Rotaries for the New Englanders). In some areas there is one after another after another after another. They really increase traffic flow.

Re: 2016 Owners...how's the stop and start working?

The stop/start on my '16 SRT8 works just fine... As soon as I got it, I started having to stop at gas stations a lot more than I did with my '14 Overland V6😂😂😂

I agree 100%. It's funny you guys mention the traffic lights because I was talking to a guy at work yesterday about that exact thing. I said that they really need to develop a smart technology traffic system. Some of these lights are absolutely obsurd how hey function. On my commute at 5am in my early day shifts or driving home at 10:30pm on my afternoon shifts with no traffic I actually go through reds. Some of you may flame me for this, but the lights are so messed up that it will literally change to red as I'm approaching and make me sit for literally minutes....no other car in site. It works 100% opposite as it should. I blow these lights all the time (obviously at the times when there are no other cars in site and is safe to do so).
The other thing that drives me nuts is say I'm driving down a sorta busy 4 lane road that has a 45mph speed limit. Nothing is worse than yourself, 15 other cars and a few semis all have to slam on their brakes all because one little Honda Civic triggered the light to change. I know you can't expect a car to sit forever, but a smart light system should be able to work so that this rush of vehicles can go through, then change once they are all through. Can you even imagine the amount of emissions and fuel that would save, not to mention time?

Re: 2016 Owners...how's the stop and start working?

LOL... every light I have to pass through is out of sequence to the normal flow (speed) of traffic. And I can relate to having 50 vehicles stop so one vehicle coming up to the lights can make a left turn. I've never driven in another area that caters to cross traffic as much as we do.
